"Judicial intervention in the functioning of anti-corruption bodies reflects both the strength and limits of the separation of powers doctrine in India." Discuss with reference to recent High Court directions on state vigilance agencies.

Article 226 empowers High Courts to issue writs "for any other purpose" [6], making even investigative agencies judicially answerable. The Madurai Bench's direction to Tamil Nadu's Chief Secretary to review the Directorate of Vigilance and Anti-Corruption (DVAC) [2] shows judicial review functioning at its strongest — yet also marks where the court must stop.

Strength: judicial review as an institutional corrective

• Accountability of the accountability-enforcer: DVAC, created in 1964 under the Personnel and Administrative Reforms (N) Department, investigates offences under the Prevention of Corruption Act, 1988 [1][3]. Judicial scrutiny ensures the watchdog is itself watched.
• Breaking executive inertia: the court flagged "recurring institutional deficiencies" and ordered a Chief Secretary-headed committee within four weeks, a report in four months, and a government decision in three months thereafter [2] — time-bound discipline the executive had not self-imposed.
• Precedent: Vineet Narain (1997) similarly used continuing mandamus to insulate the CBI and confer statutory status on the CVC [5], echoing the Second ARC's "Ethics in Governance" call for autonomous anti-corruption machinery [4].

Limits: the court directs, it cannot administer

• Design, not delivery: the court ordered a review; the committee's composition, findings and implementation rest with the executive [2].
• No power over the purse or posts: capacity gaps — staffing, technology, preventive vigilance [2] — need budgetary and legislative action beyond judicial competence.
• Risk of over-reach: sustained supervision of an executive department strains the basic-structure principle of separated functions; enforcement of such orders remains weak without political will.
• Structural gaps persist: prior sanction requirements and Lokayukta weaknesses are legislative questions, not writ-remediable ones [3][4].

Judicial intervention is thus a catalyst, not a substitute — it opens the reform window that the legislature and executive must walk through. Statutory autonomy, secured tenure, adequate staffing and transparent reporting, as the Second ARC urged [4], would let vigilance agencies deliver probity on their own strength, keeping separation of powers cooperative rather than corrective.
